Extracting Data From Predictable String Input?
Oct 11, 2011
However a coworker and I are wanting to build a separate program instead of just running simple scripts.I'm running into the following problem:I am not sure how to program visual studio 2010 to the extent that when we paste in predictable text structures that it will take only certain items out of the text, assign them to variables that we can call later.Example:We log into a lot of UBRs for testing and the structure is basically thus:

Does anyone know of a way that you can get the string that is held at this reference point (its the contents of a registry value that corresponds to a string - see this thread for more info [URL]
@%Systemroot%system32wbemwmisvc.dll,-204
I think I've seen C# (or maybe C++) code use lines like this but I cant find any way of getting the value from the DLL in VB.NET

My program uses the serial port to receive characters as a string, then it should extract the integers from this string. This seems fairly simple, but so far has been a very tedious job.
My string is called txt. The problem is that there's no telling how many characters / integers txt will hold at any given moment. For instance, it may equal "4" or "4 5 6 7" or "P 0 1 2 3 4 5 6...255" - with spaces included. I need to reference every number within this string to use as data. I've tried the following:
dim c as new char
dim n as new integer
dim i = 1

This is my second post on this topic. I included all the code this time. In calculate click event the value is zero and I don't understand where I went wrong. My work is due tomorrow, if anyone can tell me why I can not extract the price from the string. What this program is doing is taking items from the stockListBox and adding them to the shoppingList Box then extracting the price from the shoppingListBox and adding the prices together.t a note- in public class I changed the string and seperated the price from the item, not sure if I was suppose to do that.lso, everything works except the calculate event.

I m trying to write a program that is mostly dynamic. This program enables the user to read in several inputs (temperature, pressure .) and perform calculations on those inputs. After that the program sends an integer to an analogue output port. The program automatically determines the number and type of the inputs. It also creates something called a variable handle for each input.This is then saved to an array input_handler(0,x). That array is sized this way input_handler(0 to 1 , 0 to 9)
0= handle (integer)
1= value (integer)
The program dynamically creates a button for every input. There also is a button for every mathematical operator. This way the user can create a function by pressing buttons.This function will be saved to a string. That string will look something like this input_handler(1,0)+ input_handler(1,4)/ input_handler(1,3)Well now Im stuck with a string and VB will obviously just print out that string instead of calculating anything. Is there any conversion I can perform so that string becomes the actual array values?

I am using an API (WSUS) that will give me an XML fragment that I need to work with. Essentially, I need to go through the fragment element by element, identify what type of element it is, and then put that element into the datagridview. The goal is to have a column with a human readable interpretation of the element, plus that actual element itself in a hidden column for further processing. So, using the below XML, I want the DGV to have column that says "Begin Or Group" and a hidden column with "<lar:Or>".
I can get an xmltextreader to loop through the elements just fine, but I can't figure out a way to return just the current element in XML. I've tried ReadString, Value, ToString, and a bunch of other stuff but just cannot seem to figure it out.
Here's an example fragment:
<lar:And>
<lar:Or>
<bar:WindowsVersion Comparison="EqualTo" MajorVersion="5" MinorVersion="0" ServicePackMajor="4" ServicePackMinor="0" />

Basically this is my problem, showing the results of a string. I am making a program for a customer and he wants to be able to extract a string or set of emails from a large group of text. In this case he wants to be able to copy a webpage and extract all the emails out of the webpage. The problem i am having is showing the results of the List(of string) Function. So far, I can copy the page, paste the content to a textbox and then i have a function that is supposed to filter out the emails and paste or Show them in a list box.
I dont know why but no matter what I do I always get this error:
Error1Value of type 'System.Collections.Generic.List(Of String)' cannot be converted to 'String'.
This happens when I try to output the return results to a textbox or list box.
Here is the code for the whole program:
Entire Program Code:
Imports System.Text.RegularExpressions
Public Class Form1
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

I have a text file I'm trying to pull specific data from to make a report in excel and am wanting to know if my code can be improved or if I have something wrong. If it's apparent to anyone that I should be doing something elThis code does work but, very slow. These reports take up to 20 minutes for about 100 files so I am wanting to decrease the time somehow. I have attached the whole sub in a text file, it's about 900 lines long so don't think I should post all of it. This is one part that seems to take the longest:Partial code that reads the text into a string, then each line is read to find whether it holds the data or not. Inside this while loop, I am checking numerous lines to see what they hold and extract specific items. First I verify it's a interface by checking for "line protocol".

While (str.Peek <> -1)

Here is what I did.
1. Went to data source window and clicked "add new data connection"
2. Choose Data Base clicked next
3. Clicked Create Typed UserInformation as the name
4. Next.... Under Data set name I typed UserInformation again
Does naming the database and the data set the same cause problems?
5. Created New Table called users for UserInformation Database.
6. I added the following Columns: FirstName, LastName, Address, and Phone
7. Edited the table to add a couple of people. Tom/Franks/108 blah street/5555555 and Bill/West/109 blah street/5555555.
8. I also reconfigured the data connection in the data source window to show the users table.
I have four labels on my form, a text box, and a button.
I want to be able to search the database by last name for what the user typed into the textbox when they click the button.
I know this is probably easy for all of you but I am still trying to get used to using databases.

I need to convert a VB6 application into VB.Net Windows application. The program pulls data from MS Exchange (UserID, firstname, lastname, etc - not the emails themselves) and places it in a .txt file. The code has been converted, but the program does not work. When the application is run, the .txt file is created, but is blank and I get a pop-up that shows the following, "trying to access email in outlook do you want to allow this?". The popup box is gone in an instant and when I try to click on yes, it does nothing. I always have to end the program as it is non-responsive.

Im trying to extract predominately table data from a PDF file, however, I would also like the option to extract image files (such as graphs, etc) as well.Is it possible to extract data from PDF files using a VB.Net application? Im trying to get this process as automated as possible, so Im trying not to use 3rd party applications such as pdf file convertors or in-line pdf readers.
Are there any free, or relatively cheap PDF data capture API's/code snipets that I can use to import data from a PDF file? Another option is to export PDF data/images into an excel spreadsheet. Is there a .Net tool that will allow this?

I cannot figure out how to incorporate the number of days into the input box then get it to loop and count the number of times the User inputs in the number of days. Then I have to incorporate it into the equation to get the total distance D = MPH * Hours. What I have right now wil not count up the number of days and locks up after I input one number and will not add anything to the listbox. Because I also have to make sure that they cant add nonnumaric values and the number of hours per day cannot exceed 20. I have put things in and taken them out but it has been 2 days and I am lost now

All I've been able to do is create the form. We have to get information off of a website and load certain information back into the textboxes on our form.
Assignment 6 - Text Parsing Many applications require you to extract information from a block of text. We will be using this heavily in the project. This project is designed to give you some practice extracting information out of text files. You will need to open up a file, search the file for some specific content, and then copy that content and place it on screen.
Go to Jobs.com and select a state that starts with the same letter as your last name (if there is no state that starts with the same letter, use the second letter, then the third letter, etc.). For example if my name was 'John Byway', since there was no B or Y, I would pick a state starting with W - either Washington, West Virginia, Wisconsin, or Wyoming.
The idea is you want to extract all the jobs information out of the page. We want to put the jobs names in a combo box, so the use can pick any of the jobs. Ideally, this would also show the information about each job. You don't need to do that. However, you do need to extract the information and put it on the screen (When you load the next job, the old job information will be lost, and you will be left with the information about the last job loaded)
Tasks
1. Go to the above address, view the source in the browser, copy and paste it into a text file. You do not need to access the Source of the web page within your application.(in IE go to View / Source; In FireFox go to View / Page Source)
3. Extract each job title and place the name in the Combo box.
4. Find and extract the following fields. Note, some jobs may not list all of these. In that case, get as many as are presented.
a. Date
b. Title of job
c. Company
d. Location
[code].....
Indicate on screen how many jobs you found. Note, you only need to look on the first page of jobs?
